1 Claim. (Cl. -410) The object of the invention is to provideimprovements in scouring and scrubbing devices, and especially in adevice that is designed and particularly adapted for the cleaning ofbathtubs, kitchen sinks and the like with their widely differing degreesof curvature.

Another and more detailed object is to provide one form of a device ofthis class, which essentially comprises a relatively rigid head, meansto quite loosely and de tachably secure to the periphery of said headthe marginal portion of a cloth or the like, means to hingedly secure asuitable handle to said head, the relative movement of said handle withrespect to said head being limited to a predetermined angle, andapertures in said head to permit liquid to flow into and from thevariable space between said head and said cloth, as said cloth swishesloosely to and fro transversely of said head, during the usualreciprocatory movement of the device.

With the objects thus briefly stated, the invention comprises furtherdetails of construction and operation, which are hereinafter fullydescribed in the following specifications, when read in conjunction withthe accompanying drawings, in which Fig. l is a diametrical section of adevice comprising the invention with the handle shown in elevation; Fig.2 is a fragmentary section on the line 22 of Fig. l; and Fig. 3 is arear plan view of the head plate per se.

Referring to Figs l-S, an annular head plate 1 preferably formed ofplastic material is shown as of generally concavo-convex shape, toprovide an outwardly curved operating surface 2, comprising a sphericalsegment whose radius is preferably equal to or less than that of themost abruptly curved portions of the surface of a bathtub or the like.The inner or rearwardly directed surface 3 of said plate is concavelycurved so as to provide a recess or partial housing, so that a centrallypositioned integral boss or shoulder 4 can be wholly within the plane ofthe periphery of said head plate. Said boss has a central rear recess orcavity 5 into which extends one end of a handle 6, that is maintained inangularly oscillatable relation to said boss by means of a suitable pinor bolt 7, that extends through both said handle end and thediametrically opposite Walls of said cavity 5, the lateral limits of thewalls of said cavity being operative to limit the angular movement ofsaid handle with respect to said head plate to a predetermined degree.

By this construction and relationship of the two parts, when holding thehandle in given positioii, said head 2,790,193 Patented Apr. 30, 1957plate will be free to oscillate within sufliciently wide angular limits,as to permit the outer surface of said plate to conform to changes andvariations in the curvature of a bathtubs surface. However, if the userdesires to apply increased local pressure to a particular portion ofsuch surface, increased pressure in either opposite direction in a planetransverse to the axis of said pivot pin will permit one portion oranother of the periphery of said plate to be pressed more positivelythan otherwise against the bathtub surface, as for abrading and removingsome particularly obstinate accumulation of foreign matter. 7

Said head plate is preferably provided with spaced radial apertures 8 topermit the passage of water or other liquid through said plate, while aplurality of, circumferentially spaced integral shoulders 9 upon therear of said plate, and adjacent to its radially outer limits, areprovided in each instance with one element 10 of a snapfastener unit,the other element 11 of each such unit being carried by the marginalportion 12 of a preferably annular scouring cloth or the like 13, thatis preferably car ried loosely across the outer face of said plate, asindicated in dash-and-double-dash lines in Fig. 1. With thisrelationship the central portion of said cloth switches back and forth,as said head plate is moved to and fro across and in engagement with thesurface of a bathtub, or other unit to which it is adapted, as forexample the various shapes of kitchen sinks, washtubs, etc.

Having thus described my invention, what I claim and desire to protectby Letters Patent of the United States is:

A scouring device, comprising the combination of an annularconcave-convex head plate having peripheral inwardly directed thickenedreinforcing portions the rearmost surfaces of which lie in a'plane, anintegral boss having an elongated recess and carried by the rearwardconcave surface of said plate and lying within the plane of its saidperipheral portions, a handle pivotally connected to said boss withinsaid recess, said handle being engageable with the opposite freed endsof said recess to limit the relative angular movement of said handlewith respect to said boss, a plurality of spaced apertures extendingthrough said head plate, a scouring cloth of substantially greaterextent than and extending loosely across the outer convex face of'saidhead plate, and snap fastening means to detachably secure the peripheryof said cloth to the thickened reinforcing peripheral portions of saidplate. a
